Abstract

Described herein are battery assemblies that comprise lithium-metal electrochemical cells and lithium-ejecta containment components. A litliium-ejecta containment component is configured to preventorat least reduce the migration of lithium metal that lias been ejected from any of the lithium-metal electrochemical cells. For example, a lithium-ejecta containment component can be positioned between a pair of lithium-metal electrochemical cells and/or between the battery-assembly enclosure and each cell. In the same or other examples, a lithium-ejecta containment component can be integrated into the battery-assembly enclosure and/or cell enclosures. Furthermore, a lithium-ejecta containment component can be configured to absorb and contain the ejected lithium metal. In further examples, a lithium-ejecta containment component is configured to direct the ejected lithium metal away from the battery assembly. Various materials, which are resistant to lithium and capable of withstanding high temperatures, can be used for a litliium-ejecta containment component
